April 15 - known to most citizens as the day tax returns are due - is a state holiday in Maine and Massachusetts. The Patriots' Day holiday celebrates the battles that began our nation's fight for independence. The real Patriots' Day is April 19, but the day is officially celebrated in these two states on the nearest Monday, which this year is April 15.
It was actually on April 18, at 10 p.m., when the famous lanterns were lit in Boston's Old North Church signaling to Paul Revere the movement of the British up the Charles River to Cambridge. Then on April 19, the shot heard 'round the world was fired and the war for our nation's independence had begun.
So what does this history lesson have to do with taxpayers outside of Maine and Massachusetts? Due to the changes in duties at IRS service centers, residents of several states are filing tax returns at a new address this year.
Taxpayers in Michigan, Rhode Island, and New York (except for all boroughs of New York City, and residents of Nassau, Rockland, Suffolk, and Westchester counties), will file tax returns this year in Andover, MA and thus are granted the extra day, until April 16, to file their return. Residents of Massachusetts also file in Andover and are granted the tax holiday. Residents of Maine file in Philadelphia this year, but are granted the holiday because the Maine post offices will be closed on the 15th.
To decrease confusion, the IRS is extending the filing deadline for estimated taxes for residents of these states as well, even though the estimates are not filed in the same location as the tax return.
Taxpayers in Connecticut, New Hampshire, and Vermont who used to file their tax returns in Andover have been assigned a Philadelphia mailing address and will no longer benefit from the Patriots' Day tax holiday.
